Using ZCMD :

pawn Код:

CMD:healme(playerid, params[])
{
    new vehicleid;
    if(!IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid, -1, "You are not in a vehicle!");
    vehicleid = GetPlayerVehicleID(playerid);
    if(GetVehicleModel(vehicleid) == 498) return SendClientMessage(playerid, -1, "Your Message");
    RepairVehicle(GetPlayerVehicleID(playerid));
    return 1;
}

Strcmp :

pawn Код:

if(!strcmp(cmdtext, "/healme", true))
{
    if(!IsPlayerInAnyVehicle(playerid)) return SendClientMessage(playerid, -1, "You are not in a vehicle!");
    new vehicleid;
    vehicleid = GetPlayerVehicleID(playerid);
    if(GetVehicleModel(vehicleid) == 498) return SendClientMessage(playerid, -1, "Your Message");
    RepairVehicle(GetPlayerVehicleID(playerid));
    return 1;
}

This should work out (I just made this command so it may not work) (Not Tested).
